Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed November 18, 1919. Serial No. 338,950.

To all whom it may concern:

Be it known that I, SOPHIA B. JoHNsoN, citizen of the United States,'residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Bedpans, of which the following is a specification.

This invention has for its object to provide a bed pan adapted to be conveniently applied to a patient occupying a horizontal position, without lifting the back-side of the patient, the form of the pan being such that it is adapted to perform its functions without liability of wetting or soiling either the patient or the bedding.

The invention is embodied in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification,

Figure 1 is a top plan view of a bed pan embodying the invention.

Fig. 2 is a section on line 2-2 of Fig. 1.

The same reference characters indicate the same parts in all of the figures.

The base or bottom 12 of my improved bed pan is substantially elliptical and is formed to rest horizontally on a bed. Rising from the margin of the bottom is a substantially elliptical curb 13, the upper edge of which forms an elliptical open seat 14:, arranged in a plane which is inclined relatively to the plane of the bottom, so that the inner end portion of the seat or that portion which is nearest the head of the patient when the pan is in use, is relatively near the plane of the bottom, and the outer end portion of the seat or that portion which is nearest the feet of the patient is elevated above said plane, the I relative positions of the bottom and seat being substantially as shown by Fig. 2.

The height of the lowest portion of the seat above the plane of the under surface of the bottom is preferably about two inches, and the height of the highest por tion of the seat above said plane is preferably about seven and one half inches. These proportions enable the pan to be operat vely applied to a body in a horizontal position without the necessity of lifting the back side of the body, and insure a comfortable and efiective position of the seat 14:.

The bottom 12 is provided with an up standing segmental lip 15 which is spaced from the lower portion of the curb 13. A

matter overflowing from the well and prevent such matter from contacting with the patients body and the bedding. The said intermediate portion of the bottom is preferably thickened as indicated at 12 to provide additional strength. The higher portion of the curb 13 is formed to deflect liquid downward and conduct it into the well, and thus additionally protect the body and bedding. To this end, I so form the higher portion of the curb that its upper portion is curved inward and overhangs a portion of the space bounded by the curb, thus forming an inclined channel 18 adapted to lead liquid to the opposite side portions of the well 16, and preventing it from spattering over the seat 14. The curb may be provided with an internal segmental rib 19 below the channel 18, the ends of said rib merging into opposite side portions of the curb. The rib 19 forms the upper margin of an inclined channel 20 also adapted to lead liquid to opposite side portions of the well. When the rib 19 is employed the channels 18 and 20 constitute respectively an upper and a lower channel.

It will be seen by reference to Fig. 2, that the lower portion of the curb 13 is in such close proximity to the bottom 12 that the pan is not liable to be tipped to depress the lower portion of the curb and incline the bottom by pressure of the patients body on the lower portion of the curb.

I I claim:

1. A bed pan having an elliptical curb rising from the bottom, the upper edge of the curb forming an elliptical open seat arranged in a plane which is inclined relatively to the plane of the bottom, so that the inner portion of the seat is relatively near the plane of the bottom and the outer portion of the seat is elevated above said plane, the pan being provided at its bottom portion with a well, and the higher portion of the curb being provided internally with an inclined channel formed to conduct liquid to the well.

2. A bed pan having an elliptical curb rising from the bottom, the upper edge of the curb forming an elliptical open seat arranged in a plane which is inclined relatively to the plane of the bottom, so that the inner portion of the seat is relatively near the plane of the bottom and the outer portion of the seat iselevated above said plane, the pan being provided at its bottom portion with a well, and the higher portion of the curb being provided internally with an upper and a lower inclined channel, each formed to conduct liquid to the well.

3. A bed pan having an elliptical bottom, an elliptical curb rising from the bottom, the upper edge of the curb forming an elliptical open seat arranged in a plane which is inclined relatively to the plane of the bottom, so that the inner portion of the seat is relatively near the plane of the bottom and the outer end portion of the seat is elevated above said plane, the bottom being provided with a segmental lip spaced from the lower portion of the curb, a portion of the bottom, a portion of said curb and said lip forming an elliptical well, the said lip, a portion of the bottom, and a portion of the curb forming a catch-basin between the well and the lower portion of the curb, adapted to receive matter overflowing from the well, the higher portion of the curb being formed to deflect liquid downward and conduct it into the well.

In testimony whereof I have affixed by signature. 7

SOPHIA B. JOHNSON.
